Image data display on an information carrier

Abstract

The invention relates to an information carrier (101) intended to be put into a rotary motion, said information carrier (101) comprising: display means (102) designed to display image data, said display means (102) being spatially located by a spatial position, processing means (103) for periodically sending to said display means (102) image data having the same spatial position as said display means (102). Use: Optical disc / Optical disc player

Description

FIELD OF THE INVENTION [0001] The invention relates to an information carrier intended to be put into a rotary motion. [0002] The invention also relates to a player apparatus for playing such an information carrier. [0003] The invention may be used in the field of optical discs for displaying a still image on an optical disc in a player apparatus. BACKGROUND OF THE INVENTION [0004] Information carriers such as optical discs comprise visual data mapped on the surface opposite to the reading surface. In particular, visual data may correspond to the label of the record or the table of contents (TOC). These data are only visible to a user when the disc is not rotating. [0005] The Japanese Patent published under number 11-250644 describes a disc player comprising means which allow to see the label of a disc when rotating. To this end, the player comprises means for flashing a label face once per revolution so that the label can be seen as an apparently still image by making the afterimag...

Benefits of technology

[0014] The periodic sending of image data allows to obtain a continuous afterimage so that the displayed image appears to be still to a user looking at the disc player. This invention is based on the property of the human eye of integrating visual information, but compared with the prior art, means for obtaining an apparently still image are directly put on the disc itself. Thus, such a solution does not need flashing means, which allows to reduce the size of a player apparatus intended to play an information carrier according to the invention.

[0021] If the calculation means for calculating the angular position are implemented in the information carrier, the data exchange with the player apparatus is limited, which allows to decrease the complexity of such an apparatus and eases the use of information carriers according to the invention in existing player apparatuses.

[0022] If the calculation means for calculating the angular position are implemented in the player apparatus, the cost of information carriers according to the invention is reduced.

[0026] This type of display can reproduce the content of the image data while ensuring an easy addressing and / or a small thickness of the information carrier. If these displays correspond to LCD displays, the power consumption is reduced significantly.
